The engine/prop turns the opposite direction than the others, left instead of right.

YUP!

Some Bf-109 versions also had a counter clockwise rotating prop, but those engines don't exist anymore.

Near Ft Worth there is a Bf-109 (it did fly) which also had a counter clockwise prop, but those engines could not be found. They replaced the engine with a clockwise one, but this one was extremely hard to fly as the tail has a certain angle to oppose the effect of a counter clockwise rotating engine. Get it?

We are expecting to get the F-82 in the game. It did have contra-rotating props. This really matters for forward-firing ordnance. A couple of guys I flew with in the F-100 had been operational in the F-82 and said it was great-hitting bird. I had one flight, flying the B-25, which had props turning same direction, and was not bothered by yaw, We did not fire any ordnance. The OV-10 was a close-coupled bird which had contra-rotating props. It had great power so this was quite significant. I had a handful of missions in it over Laos for forward air control orientation, firing marking rockets. Rockets much align into the wind in the first few feet so yaw is a serious problem when accuracy matters. All the pilots from the OV-10, with whom I had contact, really liked it.
